Transmission Reprogramming Kit

The Performance 5R55W-HD2 is a high-performance valve body reprogramming kit specifically engineered for Ford 5R55W and 5R55S transmissions, with some sources indicating compatibility with 5R55N models from 1999-on, though one source explicitly states it *does not fit 5R55N*. This comprehensive kit addresses common transmission issues such as won't move, pump noise, no lock-up, and slips or shudders in lock-up. It also helps correct diagnostic trouble codes including P1740, P1744, P0732, P0733, P0734, and P0735. The 5R55W-HD2 includes a no-noise pump flow control valve assembly, an upgraded TCC/lock-up valve assembly, a pump alignment tool, EPC relief assemblies, high-temperature low-shrink direct clutch rings, and reamers with oversize valves and guides for precise installation. It also contains springs to address no/slow reverse and loss of various forward gear ranges. Transmission removal is optional for installation, and the kit is presented as an optional internal upgrade. It is noted as a perfect addition for Mustangs with power and is suitable for performance and tow/haul applications. The kit simplifies the ordering process by including all essential high-wear components for a full overhaul or preventative maintenance.
